Got it, ​https://developer.wordpress.org/reference/hooks/pre_comment_user_ip/#comment-4830, this example has a little problem.

After I change it as below, the issue is fixed.

add_filter( 'pre_comment_user_ip', 'auto_reverse_proxy_pre_comment_user_ip');
function auto_reverse_proxy_pre_comment_user_ip($comment_author_IP) {
    if( is_admin() ){
        return $comment_author_IP;
    }
    
    $REMOTE_ADDR = $_SERVER['REMOTE_ADDR'];
 
    if (!empty($_SERVER['X_FORWARDED_FOR'])) {
        $X_FORWARDED_FOR = explode(',', $_SERVER['X_FORWARDED_FOR']);
        if (!empty($X_FORWARDED_FOR)) {
            $REMOTE_ADDR = trim($X_FORWARDED_FOR[0]);
        }
    }
 
    /*
    * Some PHP environments will use the $_SERVER['HTTP_X_FORWARDED_FOR'] 
    * variable to capture visitor address information.
    */
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
        $HTTP_X_FORWARDED_FOR= explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
        if (!empty($HTTP_X_FORWARDED_FOR)) {
            $REMOTE_ADDR = trim($HTTP_X_FORWARDED_FOR[0]);
        }
    }
 
    return preg_replace('/[^0-9a-f:\., ]/si', '', $REMOTE_ADDR);
}

Thanks for circling back and explaining the solution to your issue!

@lxtx below that code example on the reference page you linked there is an option to leave feedback. Do you mind just noting the issue with the example that you discovered there for others attempting to use the same example in the future?
